Mirror light baffle replacement

I'm looking to replace the mirror's light baffle on a Canon Ftb and Nikkormat FT3 body. Reading Micro-Tools site, the dimension are apparently for the width of the foam, not the height. Are the height's all the same? Also what solvent could I use that I have or can buy locally to remove the existing adhesive? Should I buy the baffle with the adhesive on it or without?

Hi, I bought a foam replacement kit from a guy on ebay (do an advanced search on seller "interslice"). It comes with different types of foam and instructions. Also the seller is very helpful if you have any questions.
